----------------------------------
Summary: An exception should be raised if the result is outside
the range of decimal
Key: HIVE-18291
URL: https://issues.apache.org/jira/browse/HIVE-18291
Project: Hive
Issue Type: Sub-task
Affects Versions: 2.3.0
Reporter: Marco Gaido

If the result cannot be represented exactly in the result type, then whether it
is rounded
or truncated is implementation-defined. An exception condition is raised if the
result is
outside the range of numeric values of the result type, or if the arithmetic
operation
is not defined for the operands.

Currently Hive is returning NULL instead of throwing an exception if the result
is out of range, eg.:
{code}
> select 1000000000000000000.000001*1000000000000000000.000001;
+-------+
| _c0 |

| NULL |

{code}
